Which number can you add to get a sum of 0 A . -10 B. -5 C. 0 D. 5

1 answer:

4 0

To figure this one out, my pre calculus teacher said to "plug and chug". Since you are adding each number to itself, A=-20, B=-10, C=0, and D=10. So your answer would be C.0

IM SICK OF ALL THE FAKE LINKS! Can I get help?

Virty [35]

Answer:

equation: 28 = 2h+ h + h or you could say 28 = 4h

h= 7

Step-by-step explanation:

since both lines are the same length they equal each other.

to get h = 7 you have to solve the equation you made.

28 = 4h

28/4 = 4h/4

7 = h

When graphing the inequality y ≤ 2x − 4, the boundary line needs to be graphed first. Which graph correctly shows the boundary l

Volgvan

Answer:

See Below

Step-by-step explanation:

The boundary line follows the graph of y = 2x - 4 because it represents the line of maximum or minimum values the graph could take. y = 2x - 4 has a y-intercept of -4 because it is in slope-intercept form. It also has a slope of 2, so to find another point on the line, you can go up two and right one. Also, this inequality has a solid line because it is "less than or equal to" and a solid line represents the values that equal.

In 2020, there were about 260 million gas powered cars on the road. This number isexpected to decrease at a rate of 1.1% per yea

Amanda [17]

This is an equation of exponential decay

y(t) = a b^ t where a is the initial amount

b is the decay factor

t is the time in years

b is found by taking 1 and subtracting the percent it decreases in decimal form

Letting t =4

y(t) = 260 million * ( 1- .011) ^ 4

=248.7473796 million

=24874737.96

Rounding to a whole number

= 24874738
